Is it safe to cut steel with a miter saw?

I have a small project and I need to cut 3/4" steel square tube. I already own a miter saw, and I don't have the space or otherwise a need for a dedicated tool for cutting metal. I was hoping to just pick up a metal-cutting circular saw blade and use that.

My googling seems to either tell me it will cut like through butter or it will explode in my face and set fire to the house and my wife will leave me and take the kids with her.
